超高效電(dian)機(ji)(ji)實際上就(jiu)是(shi)“精品電(dian)機(ji)(ji)”，效率的(de)實現從理論上來(lai)說方法很多(duo)，但(dan)最重要的(de)是(shi)工藝保證程度。電(dian)動機(ji)(ji)效率不斷提高的(de)過程是(shi)產品不斷更(geng)新換代的(de)過程，同時也是(shi)一個國(guo)家電(dian)機(ji)(ji)工業綜合水平的(de)標(biao)志。
高(gao)效電動(dong)(dong)機的設計要點就是要降(jiang)低各項損(sun)耗(hao)，提(ti)高(gao)電動(dong)(dong)機效率(lv)。所采取的措施包(bao)括：應用特(te)殊下線工具，提(ti)高(gao)定子槽(cao)滿率(lv)，增加了銅線的截面積；提(ti)高(gao)制造(zao)精度(du)，縮短(duan)線圈(quan)端部(bu)長度(du)，加強沖(chong)片(pian)和(he)定子鐵(tie)心的制造(zao)質量，從(cong)而(er)減少鐵(tie)耗(hao)和(he)激磁(ci)電流及其(qi)引起的銅耗(hao)；改(gai)善轉子槽(cao)絕緣工藝，降(jiang)低負(fu)載雜耗(hao)；合理的選(xuan)擇硅(gui)鋼片(pian)的牌(pai)號，降(jiang)低鐵(tie)損(sun)和(he)定子銅耗(hao)。
